Brilliant from start to finish. From a quote late last year I contacted the original and he came that day to give me a new quote. Marcin got me a fab deal. Top lad. The fitters were friendly and efficient and everything looks amazing. I was that impressed with the work done as its substantial expense! Highly recommend.

Trustpilot

I normally do not bother with reviews but this one is well deserve. From challenging and complex design to exceptional delivery Grabex have delivered both prearranged glazing phases of our own little grand design project. Service, and what most important huge level of patience to work with us is just much appropriated. We are very pleased to have agreed lead-time delivered what that we did not experienced from other contractors working on the project. Product is fantastic, looks better than in showroom, joinery shop visit was educating and very interesting - never been to factory. We can now enjoy new glazing - let’s hope now rest of trades will follow. Big Thank you for all involved.
